1. 46 Melting Point The temperature at which the metal will begin to melt The molten metal of the weld pool will be at this temperature during the welding process Boiling Point If enough energy is added to the weld joint and heat is removed slowly by the surrounding solid metal the weld puddle can begin to boil Liquid metal will be turned into gaseous metal Specific Heat The energy required to raise the temperature of the metal per unit mass Think of this number as how much metal will melt for a given weld energy melting point also is important A larger specific heat means more energy is required to melt the metal Electrical Resistivity This number represents the resistance to the flow of electrons in a metal This property is especially important during a resistance or tack weld The more resistive the metal is the more easily it will resistance weld e g stainless steels the smaller this number is the more difficult it will be to weld the material e g silver especially in tack mode Density how much of the metal atoms mass is in a given volume of space This property will also influence how large the weld spot is for a given metal All other things being equal a lower density metal will have a larger weld spot than a higher density metal for the same weld energy Thermal Expansion When a metal is heated it will expand or elongate slightly In some situations especially during resistance

3. The first is the surface tension of the molten metal Surface tension is a force between the metal atoms themselves that is pulling the molten pool of metal flat during the metal s liquid phase Metal surface tension when molten is many times stronger than water surface tension The second force as work happens when the weld plasma exerts a force on the molten metal as the plasma s electrons bombard the weld surface Electrons from the plasma will attempt to push the molten metal in the direction the electrode tip points Surface tension and plasma electron pushing are generally competing forces The plasma tries to push the molten metal while the surface tension tries to keep it in place This means 1 Some metals with lower surface tension e g silver are easier to push around than metals with high surface tension e g Stainless 2 Surface tension itself can be used to move metals around By placing the electrode between a high and low spot the melting process will try and flatten the two stealing material from the high and moving it toward the low The surface tension smoothing is accomplished by placing the electrode at a 90 deg angle from the work piece surface with the electrode tip on the edge or slightly interior to the edge of the metal mound The welding process will then take material from the mound and spread it 61 62 into the surrounding material One should repeat this process until the prope

5. welding metal can expand quickly and spill out of the weld joint Thermal Conductivity This is a measure of how fast the metal conducts heat Metals that are good conductors of heat e g copper will dispel the heat away from the weld location quickly during the welding process This action reduces the size of the weld spot Metals that are poor conductors of heat e g titanium are slow to conduct heat away from the weld location and the weld energy has a greater affect on the weld size etc 10 Measure of Weldability OF e Ww amp Wm Go WD This measure of weldability comes from properties of the metal like melting point thermal conductivity density etc and is intended as a relative reference between the different metals It can be thought of as how much spot size and penetration a given amount of weld power will have on the metal Please note that some metals may have properties not accounted for in this chart that may make welding more difficult than indicated e g palladium Titanium and Niobium Some metals may react easily with oxygen and even other gases like nitrogen Titanium Ti reacts with both oxygen and nitrogen at elevated temperatures Ti burns to form TiO2 in air at 1200deg C Ti will also burn in pure N2 gas at 800deg C to form TiN Titanium nitride TiN is inherently brittle which will result in a weak weld joint Very light reaction mostly shielded may just include slight discol
6. 22 Gas Options Timing Options System Options Chapter 3 Pulse Arc Welding Welding Basics The Orion is a pulse arc welder and a capacitive discharge resistance welder in one This combination of abilities allows for infinite creative possibilities The Orion can be used as a tack welder to temporarily position parts before welding or soldering By increasing the power output it can also be used as a permanent fusion welder resistance welder spot welder In its Pulse Arc Mode the Orion can be used to perform permanent welds add metal and do a variety of other amazing and time saving applications What is a Pulse Arc Welder A pulse arc welder is a special case of a Tungsten Inert Gas TIG welder In TIG welding a sharpened tungsten electrode is used in combination with electrical power to start and sustain an high temperature plasma stream an arc This plasma arc is used as a heat source to melt the work piece metal Filler metal can also be added to build up joints and create strong and reliable weld beads or weld seams TIG welders can use AC alternating current or DC direct current energy to initiate the plasma arc Orion Welders has chosen to build on our extensive experience with DC welding technology The Orion uses industrial capacitive discharge technology to produce the pulse arc weld AC wall voltage can vary up to 20 during the day Capacitive welders have the advantage over AC technologie
7. an electrode to actually perform the weld then the tip should be as small as is reasonable for the desired weld size e g 1mm spot size or less is typical Remember that when using an electrode to perform the welding process the pressure applied by the electrode tip determines the weld pressure and the heat generated A weldment or bump between the two parts to be welded can still be used to focus the energy Place the electrode directly over the weldment location remember the weldment is actually between the two sheets etc not on the electrode Chapter 5 Tungsten Electrodes THE SINGLE MOST IMPORTANT VARIABLE IN THE WELDING PROCESS IS THE ELECTRODE The Orion welder comes standard with 5 0 5mm and 5 1 0mm electrodes The 1 0mm electrodes are a good all around electrode while the 0 5mm electrode is excellent for very small projects The larger 1mm electrode allows more energy to come out at one time The smaller 0 5mm electrode may be better for cases when less energy is desired HANDS ON Make a weld using pulse arc mode at 15 Joules and 8ms using a sharp 1 0mm electrode Now make a weld using the same settings using a sharp 0 5mm tip In the HANDS ON examples above more power was transferred from the Orion into the piece for the same setting using the 1mm electrode For very small parts using the small electrode is sufficient This option reduces the peak weld current versus using the large electrode and can also allow

9. devices are good welding tools the Orion can perform many of the same functions of a laser and in some cases can even perform actions that lasers cannot For example welding silver is difficult for laser light because of silver s highly reflective properties However the Orion does not have this limitation because electrons are electrically attracted to the surface of silver The Orion also has the advantage of only welding on metal Lasers can strike precious stones or other nonmetals and can even crack or evaporate the target Because the Orion is electrically driven it requires a conductor such as a metal to allow the welding process to take place The Orion s Pulse Arc plasma is as hot or hotter than the surface of the sun 25 26 The Orion welder uses the same high temperature plasma that can be found on the surface of the sun The sun creates this plasma via internal fusion reactions and the plasma temperature measures about 5 500 deg C at the sun s surface The Orion creates it s plasma via electrical discharge and can generate temperatures of 5 500 8 000 deg C in very controlled small bursts Start Welding To become an expert and to really learn how to maximize the Orion we recommend that you dedicate time for real hands on experience We recommend that you read and complete the following sections while you are in front of the Orion The Orion is very easy to use and many users will be making quality
10. energy is set to produce only a small spot size the wire will typically fail to be added to the base material Instead the wire will ball and some melting of the base material will occur which is insufficient to add the wire Placing the weld electrode on top of the fill wire at a 90deg angle from the base material surface is typically not the preferred method of adding material If the wire is large compared to the energy setting the wire will ball due to surface tension and will not be added to the base material A top electrode placement can work if the wire diameter is small compared to the power setting In this case there is enough plasma pressure to force the molten wire down onto the base material 59 60 A final scenario can occur when the electrode is placed on top of a large wire being welded to a base material at a high weld energy setting In this case the plasma can push the wire metal down to the base metal surface but there may be no penetration into the base material Placement of the electrode directly on top of the fill wire can melt the wire into the base if the power is sufficient or the wire is very small Alternatively it may also only melt the wire causing it to ball as shown for larger wire size or insufficient power setti ngs HANDS ON Try adding fill wire using the top placement method Build up a small mound of material As a rule of thumb it is always best to use the side electrode placem
11. for a smaller weld spot For larger parts use the 1mm electrode The 1mm electrode is used when needing additional weld current more melting for same energy The larger electrode is recommended for metals such as silver due to higher welding energy requirements of such metals Please note that the 1mm electrode should be used for the normal pulse arc welding mode and the 0 5mm small electrode will burn or oxidize at higher power settings As a general suggestion the 1mm electrode is a good choice for most applications even very small ones Left Using too much power with the 0 5mm electrode will cause it to overheat and reduce its life Right A 1 0mm electrode can weld at a variety of powers without overheatin g Why Use Tungsten Electrodes 1 Hardness tungsten is extremely hard and is therefore able to hold its shape during the welding process 2 Tungsten s melting temperature is much higher than most other metals This means the metals being welded will melt before the tungsten Melting temperatures of selected metals C oo o o 37 38 The table shows a variety of metals and their corresponding melting temperatures Note that tungsten has a significantly higher melting temperature than the other metals This is an important attribute of tungsten that aids the welding process While welding electrons from the weld plasma impact the work piece and form a weld spot At the same time positively ch
12. joint The addition of the ferritic crystal structure will help suppress cracking For example when welding 304 stainless a 308 stainless fill wire can be used Not all situations will require crack suppression techniques Smaller parts like those typically welded using the Orion do not require these procedures 201 202 205 216 301 302 303 304 305 308 309 310 312 314 316 317 321 329 330 332 347 348 384 385 stainless steels Martensitic stainless steels 410 for example have a high carbon content This high carbon content increases the risk of cracking To decrease the risk of cracking it may be helpful to increase the work piece temperature to between 200 300 deg C Often material thinner than 3mm can be welded successfully without heat treatment provided that pure argon is used during the welding process 403 410 414 416 418 420 422 431 440 501 502 503 504 stainless steels Low Carbon Steels Mild Steel Low carbon steels typically weld easily with no major cautions Please be advised that low carbon steel will rust and will often come with a coating of zinc The zinc coating will cause the metal to appear more white or lustrous than typical steel As discussed above welding on zinc will cause many issues to consider The zinc will evaporate quickly from the weld area causing a black coat to spread to the surrounding metal including the welding stylus The zinc evaporation may also cause stra
13. little or no weld 2 Next clamp the parts firmly in the tool but apply virtually no pressure between the parts make sure these are parts you no longer need The result will be a very large spark or at least a much better weld 3 Practice at different energies and pressures until you feel comfortable with the process and results The pressure between the tool holding the part is also very important If insufficient pressure is applied between the tool and the part the weld may take place between the tool and the part Always grip the part firmly in the tool to reduce the contact resistance between the tool and work piece Doing this will reduce the amount of heat created where the tool and part meet Resistance Welding Tools It is always a good idea to have the resistance welding tool made from a material like copper when welding more resistive parts such as steels If using a tool to hold the work piece together remember that firm pressure between the tool and the work piece is important to prevent welding the tool to the work piece e g brass lined pliers Then apply the correct pressure between the work pieces to achieve your weld This will help to ensure the resistance between the tool and the part is very low and no weld is made at this location Typically it is not good practice to use a set of steel pliers to hold a steel part for example during resistance welding The tool can easily fuse to the work piece

15. the micro scale all surfaces have a degree of surface roughness This roughness causes the work pieces to only contact in a limited number of locations Middle Applying more pressure will cause more surface contact less resistance and less resistive heating Right Applying less pressure will cause less surface contact more resistance and more resistive heatin fg During a resistance weld the surface between the two parts being welded is not truly flat On the micro scale these surfaces are rough and only contact in a limited number of locations and the limited contact translates to an increased electrical resistance at the contact between the two parts A resistance welder uses the resistance to the flow of electricity to heat and melt the part via a large electrical current This contact point is where the highest heat is generated Light pressure 31 32 between the parts means less contact between the two surfaces more resistance and hence more heating and melting Heavy pressure between the parts translates to more contact between the two surfaces less resistance and less heating For small scale welding the melting processes typically will start at the interface between the two parts due to this high contact resistance The exception to this rule is when resistance welding conductive materials copper silver gold brass that require a tungsten or molybdenum electrode When welding with a resistive electrode tungsten

19. zinc is a hard metal to pulse arc weld or resistance weld because of its low melting and boiling temperature 420 deg C 907 deg C During the melting process the low temperature zinc evaporates boils out of the brass alloy For low energies this simply coats the surrounding material in a black zinc film that can easily be removed with a glass brush For larger pulse arc weld energies the black coat can cover larger areas and porosity can develop at the weld location as zinc boils from the weld Joining Different Metals Welding different metals together will produce a new alloy at the weld location The new alloy will have different properties although in many cases similar properties to the base metals Some metals combine well forming a strong and useful new alloy Other metal combinations are weak and brittle Helpful Hints for Combining Different Metals 1 Check the new alloy strength with scrap material to ensure the joint will turn out as expected 2 You may need to weld over the joint location several times to get complete mixing of the weld pool and a uniform new alloy In most cases this is not necessary for a strong joint and the first weld will be sufficient 3 Some material combinations may benefit from a third metal at the joint which forms a better stronger alloy with the two primary metals An example of titanium welded to gold and silver The gold to titanium weld looks clean but is brittle The silver t

Push the argon gas tube 1 4 firmly into the tube receptacle until it seats firmly into the connector Connect the microscope connector by pushing it into the Optical Unit receptacle firmly and then tightening the threads Connect the foot switch by pushing it into the receptacle firmly and then tightening the threads The Pulse Arc welding stylus must be screwed in securely to insure no oxygen is entrained into the weld This may require pushing in and screwing down the connector several times pushing it in further each time until feeling the rubber o ring seal against the Orion connector Place a welding attachment into the positive front panel receptacle e g the pulse arc alligator clip HANDS ON Please set up your Orion welder as described above 11 12 How to Setup and Use the Microscope The Shutter System The Orions microscope shutter system is an advancement over other welding systems The shutter allows an unobstructed working view before welding and completely protects the user s eyes during the welding process The Orion will not allow a weld to take place if the shutter does not completely shut If you ever experience a shutter malfunction try moving the shutter in and out several times to clear any obstructions If sticking continues a silicon based lubricant can be used to prevent future sticking By hand close the shutter and while the shutter is closed spray a small amount of th
21. Typically steel is not used for resistance welding because of steel s high internal resistance This high resistance means that a great deal of power is dropped in the tool before even making it to the weld location The exception to making a resistance welding tool from steel is when only a small amount of power is needed This may happen when only a light tack weld is needed before pulse arc welding Cables for Resistance Welding A true resistance welding hand piece should transfer as much power to the weld location as possible The Orion is capable of transferring over 3000 amperes to the weld location To enable this full power transfer 1 The welding attachment should use 3 5ft 1m of LOAWG cable 2 IMPORTANT the cable should be no larger than 10 AWG or damage to the welder may occur e g 8AWG is a larger cable Not all tack welds require this amount of energy Smaller cabled pulse arc attachments can be used for simple tack welds that require lower power Custom Resistance Welding Tools It may be helpful to shape the tool for the application Tools that clamp the parts e g brass lined pliers should have as much surface as possible in contact with the part to allow more power to transfer to the weld location Remember that the area between the work pieces should be small to focus the energy if a strong weld is desired A weldment or bump can be used to help focus the energy if desired 35 36 If you are shaping

27. ances different metals can be welded easily together with the Orion In pulse arc welding the weld spot location becomes a new alloy of the two primary metals this new alloy will adopt new properties that may be better or worse than the primary materials Dissimilar metals can also be joined in Tack Fusion Mode Again weld strength and properties will depend on alloy properties How do I determine the best power settings for my particular weld application In Pulse Arc Mode metals will weld according to thermal conductivity and melting point For example a metal with lower thermal conductivity e g stainless steel titanium cobalt alloys will weld easily because the weld heat stays concentrated in the spot Therefore less power is required to weld one of these metals than other metals of the same thickness that have a higher thermal conductivity Metals with higher thermal conductivity e g copper silver gold will require more power to create the same spot because much of the heat is conducted away quickly The melting temperature of the metal is also very important when determining the necessary power setting for a weld Knowing the approximate or relative melting temperature of your working metal will enable you to estimate the amount of energy require to create a spot High melting temperature translates to a large amount of energy required Low melting temperature translates into a smaller amount of energy required to make the
